<span>The scientist thought that the
atom was the smallest particle in the universe is John Dalton. The answer is
letter B. He established the atomic theory which consists of five; elements are
made of extremely small particles called atoms, atoms of different element have
different sizes, mass and physic – chemical properties, atoms cannot be divided
further, destroyed or created, atoms can combine to form compounds and in
chemical reaction, atoms can be combined, separated or rearranged. J.J.
Thompson discovered the electrons in the atom. Ernest Rutherford discovered the
half – life of an atom and Neils Bohr explain the quantum mechanics.</span>
The best way to deterime which cloth with absorb heat is to put each cloth outside in the heat with a thermometer under it and see which has the highest tempe.
It’s light seconds, now don’t mistake it as time
Answer:
To identify the electron transition that has the highest frequency in the hydrogen atom.Answer: The frequency of light produced by electron transition is highest among the given electron transition, therefore, the option (a) is correct.Explanation:The energy of emitted light by the electron transition is given as: is the energy of the initial level. is the energy of the final level.The energy difference for the electron transition is highest among given electronic transition.The energy of the light is given as:Here, is the plank’s constant. is the frequency of the light.The energy of the light is directly proportional to the frequency of the light.Therefore the frequency of light by the electron transition is highest among given electronic transition.
Explanation:
